SEED GERMINATOR. V I

Applieatio nrfiled November 4,1926. Seria1.No.-146,138. I

. My invention has for its object to provide a simple and highly eflicientgerminator for testing seeds as to theirrapidity' and perfection of germination, and to .such ends, it consists of the novel devices, combinations of devices and arrangement of parts hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate likeparts throughout the several views.

Referring to the drawings:

Fig. 1 is a front elevation of the improved germinator; n

Fig. 2 is a central vertical section on an enlarged scale;

Fig. 8 is a horizontal section taken on the line '3-3 of Fig. 2, with some parts broken away; and

i Fig. 4 is a view principally in section taken on the line 44: of Fig. 2.

The numeral 5 indicates a box-like base having an open top and a horizontal parti-- tion 6 located slightly below the upper edge of said base to afford a capping flange 7.

pair of passages 8 are formed in the partition 6, relatively closeto the sides of the base 5, for a purpose that will presently appear. Said partition, between the passages 8, is

' made concavo-convex and separates the base 5 into a lower water receptacle 3 and an upper heating chamber a.

top of the base 5. Artificial heat may be supplied to the heating chamber 2 by an electric light bulb 9 mounted ina socket 10 secured in the rear wall of said chamber, and supporting said light bulb in a horizontal position. A duplex lamp cord 11 is attached to the terminals in the socket 10 and, in actual usage, will be provided with a plug for attaching the same to an outlet opening.

A rectangular casing 12 is removably sup ported on the partition 6 within the capping flange 7. The entire front of the casing 12 affords a window opening 13, at the sides of which are vertical guides 14 in which are mounted a plurality of glass panes 15 loosely supported, the one upon the other, and having at their lower edge portions knobs 16 by which said panes may be raised or lowered. On the back and side inner walls of the casing 12 are pairs of laterally spaced upright Webs 17, and secured to the. side walls of said casing are shelf-supporting rods 18. Perforated shelves 19 .are removably sup- This heating chamher 2 is in the form of a depression in the ported on the rods 18,and removably supported on each shelf is anabsorbent'seed bed 20, which maybe a blotter 'oryother suitable material.

In the bottom of thecasing 12is a central. hot airpassage 21, which leads from the heating chamber 2 to the interior of the casing 12. A rectangular heat spreader on top of the spreader 22. It'will be noted that the spreader 22 is so arranged thathot air from the chamber .2 will pass thereunder and into the casing 12 at the four sides thereof and then rise between the several pairs of ribs 17 so that the heat is evenly distributed in the casing 12. A sheet of asbestos 26 or other suitable insulating material is sus A I pended from the top of the casing '12 by rods 27. On top of the casing 12 is a handle 28 by which the germinator may be carried- A plurality of absorbent sheets 29, such as blotters have their lower end portions inserted through the passages 8 and into the water a; and supported from the bottom of the water receptacle y. Theupper end portions of the two series of sheets 29 are turned toward each other over the spreader. 22.

Water is conveyed from the water recep tacle 3 to eachjseed bed 20 bytwo wicks 30 of cotton or any other suitablematerial. The

lower end portions of the wicks 30 are laid between the upper end portions of the several absorbent sheets 29 and their upper end portions are laid between the shelves 19 and seed beds 20. It will be noted that the two wicks for each seed bed 20 extend under the number of seed beds may be used, depending on the capacity of the germinator.

The purpose of making the glass closure.

for the window opening in sections is to per- :mit any-one of said sections to be raised for the removal of the adjacent shelf and seed bed thereon, Of course, when lifting the lower or oneof the intermediate glass panes,

theglass panes resting thereon will also be lifted therewith. The perforated shelves 19 permit the passage of heat therethrough so that the seed beds are evenly heated from their under sides throughout their entlre area.

means of the electric light bulb 9 or any other heating element placed on the heating chamber 2, said germinator may be placed on a radiator or over a hot air register and thus heated, or the germinator may be placed where the suns rays will strike the glass panes 15 and thus heat the germinator. Of course, the germination of seeds on the seed beds may be hastened orretardedby means of the heat applied to the germinator'.

-What I claim is: l. A seed germinator-comprising a water receptacle, a casingover the water receptacle, a shelf in the casing spaced from the'walls In place of heating the germinator thereof, an absorbent seed bedyon the shelf, a wick leading from the water receptacle to the seed bed and suspended between the shelf and walls of the casing, and a heating chamber between'the water receptacle and easing;

v 2. ,:A seed. germinator comprising a water the base closing the water receptacle and having a depression forming a heating chamber 1n the baseabove the water receptacle. In testlmony whereof I afiix'my signature.
